  According to the present invention, when the power of the device main body is restored, it is detected and the time of the built-in clock is automatically corrected.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 is a front view of a television receiver according to the present invention, FIG. 2 is a block diagram of the television receiver shown in FIG. 1, FIG. 3 is a flowchart showing an operation flow in the apparatus main body, and FIG. 4 is an operation flow in a remote controller. It is a flowchart to show.

  As shown in FIG. 1, the television receiver (set device) 1 includes a device main body 10 and a remote controller 20.

  As shown in FIG. 2, the device main body 10 includes a tuner 11 that performs tuning and tuning, a signal processing device 12 that performs various processes on video signals and audio signals, and a liquid crystal display (LCD) 13 that displays video. A built-in clock 15; a microcomputer 16; a memory 17 for recording various data; a communication unit 14 for exchanging signals to and from the remote controller 20; and a power supply circuit for supplying power to the tuner 11 and others. 18 and a power cord (AC cord) 19.

  On the other hand, as shown in FIG. 2, the remote controller 20 includes a receiver 21 that receives radio waves including time information, a radio clock 22, a keyboard 23 that performs power ON / OFF of the device body 10 and various timer settings. And a microcomputer 25 and a communication unit 24 for exchanging signals bidirectionally with respect to the device main body 10.

  Here, the communication method between the communication unit 14 of the device main body 10 and the communication unit 24 of the remote controller 20 may be either infrared or wireless.

  Since the television receiver 1 has the above-described configuration, when the apparatus main body 10 is restored, it is detected and the time of the built-in clock 15 is automatically corrected.

  That is, the microcomputer 16 of the device body 10 monitors the power recovery of the device body 10 (step S11 in FIG. 3). Here, as a technique for detecting the power recovery of the device main body 10, a method using the fact that the voltage level of the power supply circuit 18 decreases due to a power failure and the voltage level of the power supply circuit 18 recovers due to the power recovery can be considered. That is, the microcomputer 16 writes “0” as a flag in the memory 17 when the voltage level of the power supply circuit 18 is equal to or lower than a predetermined threshold value, and when the voltage level of the power supply circuit 18 exceeds the predetermined threshold value. Then, “1” is written in the memory 17 as a flag. When this flag is changed from “0” to “1”, it is determined that the device main body 10 has recovered power.

  As a result, when the device main body 10 is restored, there is a possibility that the built-in clock 15 is reset with the stop of the power supply from the power supply circuit 18. Therefore, the microcomputer 16 outputs a time data request signal from the communication unit 14 to the remote controller 20 in order to request the remote controller 20 for the time data of the radio timepiece 22 (step S12 in FIG. 3).

  At this time, the remote controller 20 monitors the input of the time data request signal (step S21 in FIG. 4). When the time data request signal is input to the microcomputer 25 via the communication unit 24, the microcomputer 25 The time data of the clock 22 is transmitted to the device main body 10 via the communication unit 24 (step S22 in FIG. 4).

  At this time, the device main body 10 monitors the input of time data of the radio timepiece 22 (step S13 in FIG. 3), and when the time data of the radio timepiece 22 is input to the microcomputer 16 via the communication unit 14, The microcomputer 16 corrects the time of the built-in clock 15 so as to match the time data of the radio clock 22 (step S14 in FIG. 3). For example, when the time data of the radio clock 22 is “10:20:30”, the time of the built-in clock 15 is also set to “10:20:30”.

  As described above, when the power of the device main body 10 is restored, it is detected and the time of the built-in clock 15 is automatically corrected. At this time, the radio timepiece 22 that captures the time information is built in the remote control 20 instead of the device main body 10. Therefore, the remote control 20 can be easily moved to a place where the radio wave reception environment is good, so Regardless of (radio wave reception environment), the time of the built-in clock 15 can be easily adjusted. In addition, unlike the case where the radio timepiece 22 is built in the device main body 10, it is not necessary to consider the electric field strength when the radio timepiece 22 is arranged.

  Further, in the television receiver 1, the time correction of the built-in clock 15 is executed every 24 hours (1 day) even if the device main body 10 does not recover power.

  That is, the microcomputer 25 of the remote controller 20 always recognizes the current time with reference to the time data of the radio clock 22 (step S23 in FIG. 4), and when the current time reaches midnight, the microcomputer 25 Is transmitted to the device main body 10 via the communication unit 24 (step S22 in FIG. 4).

  At this time, the device main body 10 monitors the input of time data of the radio timepiece 22 (step S13 in FIG. 3), and when the time data of the radio timepiece 22 is input to the microcomputer 16 via the communication unit 14, The microcomputer 16 corrects the time of the built-in clock 15 based on the time data of the radio clock 22 (step S14 in FIG. 3).

  Thus, since the time of the built-in clock 15 is corrected every 24 hours, even if the accuracy of the built-in clock 15 is not so high, almost accurate time is recorded by daily time correction. Therefore, when the timer setting such as timer recording reservation is performed by operating the keyboard 23 of the remote controller 20, the timer setting can be executed more accurately.

  Here, the time of the built-in clock 15 is corrected every day at midnight, but this time is not limited to midnight and can be set to any time according to the convenience of the user. Further, the frequency of the time correction of the built-in clock 15 is not limited to once a day, and may be twice or more a day or once every several days.

  Further, since the time correction of the built-in clock 15 can be executed only when the radio clock 22 of the remote controller 20 always receives the latest time information via the receiver 21, the remote controller 20 receives the radio clock 22. The state is always checked (step S24 in FIG. 4). If the reception state of the radio timepiece 22 is poor, the microcomputer 25 of the remote controller 20 outputs an unreceivable display request signal to the device body 10 via the communication unit 24 (step S25 in FIG. 4).

  At this time, the device body 10 monitors the input of the reception incapability display request signal (step S15 in FIG. 3), and when the reception incapability display request signal is input to the microcomputer 16 via the communication unit 14, the microcomputer 16 As shown in FIG. 1, a message 2 for prompting the position change of the remote controller 20 is displayed on the liquid crystal display 13 for a predetermined time (for example, 10 seconds) and a warning is issued (step S16 in FIG. 3).

  Viewing this, the user changes the position of the remote controller 20 as appropriate. This position change of the remote controller 20 is repeated until no warning is issued. As a result, the remote controller 20 eventually moves to a place where the radio wave condition is good, so that the time correction of the built-in clock 15 can be surely executed.

  In the above-described embodiment, the case where the time of the built-in clock 15 is corrected when the device main body 10 recovers power has been described. However, if the user does not use timer settings such as timer recording reservation, the device main body There is little need to adjust the time of the built-in clock 15 even if the power is restored. Therefore, the time correction of the built-in clock 15 may be performed only when the device main body 10 recovers power and the timer setting is accepted.

  In the above-described embodiment, the case where the message 2 is displayed on the liquid crystal display 13 when the warning that the reception state of the radio timepiece 22 is bad is described. However, the method of issuing the warning is not limited to this. is not. For example, an announcement that the reception state of the radio timepiece 22 is bad can be sent from a speaker (not shown) of the device main body 10.

  In the above-described embodiment, the case where the time of the built-in clock 15 is corrected to match the time data of the radio clock 22 has been described. However, the time of the built-in clock 15 is set to a predetermined time with respect to the time of the radio clock 22. Customization can be realized. For example, when the time data of the radio clock 22 is “10:20:30”, the time of the built-in clock 15 is advanced by 1 minute from that time for the purpose of preventing the head of the broadcast program from being cut off, etc. It may be set to “21 minutes 30 seconds”. Alternatively, when the time data of the radio clock 22 is “10:20:30”, the time of the built-in clock 15 is delayed by 30 seconds for the purpose of preventing the broadcast program from being cut off. It may be set to “hour 20 minutes 00 seconds”.

  In the above-described embodiment, the case where the time of the built-in clock 15 is corrected when the power of the device main body 10 is restored or every 24 hours has been described. You may make it correct 15 time. Although it is possible to correct the time of the built-in clock 15 each time the keyboard 23 of the remote controller 20 is operated, it is not preferable in that the time correction frequently occurs and the battery consumption of the remote controller 20 increases.

  In the above-described embodiment, the television receiver 1 has been described as an example of a set device. However, the present invention may be applied to a set device (for example, an audio device) other than the television receiver 1. Of course you can.

  The present invention can be widely applied to various set devices such as a television receiver with a remote control and an audio device. In particular, in a set device that does not have a built-in tuner, time information cannot be acquired from broadcasting, so that the present invention increases usefulness.
